如何使用可乐在 cytoscape.js 中设置边缘的长度？

Question

I am using the latest version of cytoscape.js and cola.js. When I change "edgelength" nothing happens.

how can I do this?

Answer 1

You can specify one of edgeLength , edgeSymDiffLength , or edgeJaccardLength in the layout options.

From the docs :

// different methods of specifying edge length
// each can be a constant numerical value or a function like `function( edge ){ return 2; }`
edgeLength: undefined, // sets edge length directly in simulation
edgeSymDiffLength: undefined, // symmetric diff edge length in simulation
edgeJaccardLength: undefined, // jaccard edge length in simulation

As this is a force-directed layout and you can set multiple constraints, you may not get the effect you're looking for if you overconstrain the system -- which is easy to do. Consider that constraints on some edge lengths may contradict constraints on other edge lengths.
